Will modern society slow the progress of change?

[abaris]

Do you think this acceptance of difference will slow revolutionary change?

Which acceptance exactly? We're quickly regressing to primitive tribalism. In the wake of the global economic crisis and the refugee problem.

Also, what revolutionary changes are we talking about? Other than some changes to make war more effective during the last century, with the side effect of benefitting humanity afterwards, there have been none. It has always been a slow process.
